| 摘 要： | We propose a layered image inpainting scheme based on image decomposition.The damaged image is first decomposed into three layers:cartoon,edge,and texture.The cartoon and edge layers are repaired using an adaptive offset operator that can fill-in damaged image blocks while preserving sharpness of edges.The missing information in the texture layer is generated with a texture synthesis method.By using discrete cosine transform(DCT)in image decomposition and trading between resolution and computation complexity in texture synthesis,the processing time is kept at a reasonable level.
